So I have my I1 for about 3 weeks and absolutely love it! Few weeks ago new software gets released. I am not ready to update I1, 2 remotes and 4 batts. When I start the app on my iPad I get the RED comments to update everything, but than I get the GREEN ready to fly. I have had one issue while flying, the iPad says "ATTI MODE" and I lose GPS flying, which I control the I1 and than it goes away and goes back to GPS. Than happens again. Yesterday I got a compass error so I calibrated the compass and than ATTI mode didn't happen on its own.
Is it a must to update the firmware, or can I wait till I am more comfortable?
As turbo says above, the update is not mandatory however you should note that the most recent FW addresses and fixes two important issues.
One you have already experienced in the Inspire drops into atti mode unexpectantly.
The other is the possibility of your Remote Control turning itself off mid flight. Although there have only been a handful of instances where that has happened, DJI did acknowledge there was an issue and identified the cause.
Personally, I would update to the latest FW versions with the exception of the latest app in either iOS or Android. In my opinion the latest incarnation of the apps are full of bloatware I will never use and triple the size of the program.
Aside from a different navigation layout and the pointless reintroduction of a satellite count they add nothing (in my opinion).
Some will love the toy Movie Maker rubbish and the false security blanket of satellite numbers but I prefer the existing app prior to the latest.
So.... I would say firmware yes, update. App, don't bother.
